Prediction of the arrival time of tsunami is critical for evacuating people from coastal area. Solving many related to tsunami problems is important in order to decrease negative effects of this serious disaster. Numerical modeling of tsunami wave propagation is a computational intensive problem that requiresacceleration of calculations by means of parallel processing. The Method of Splitting Tsunami (MOST) is one of the well-known numerical solvers for modeling tsunami waves in the ocean. This paper focuses on design and evaluation of tsunami simulation code using OpenCL. We have developed a tsunami propagation code based on MOST, and implemented its different parallel optimizations for GPU and FPGA.
